Energy from Coastal Wind in Bangladesh

Kutubdia:
Day by day generation of electricity from Wind energy becomes very much promising where wind speed and power density is high. In Bangladesh, mainly at coastal areas there are some Islands and Inlands also where wind energy can play an important role to improve the economy of the country. Different studies show that some inland locations and islands in the coastal part of Bangladesh have a fair potential of wind energy for electricity generation. Wind resource assessment over Bangladesh under the Solar and Wind Energy Resource Assessment (SWERA) has been done by RISOE using KAMM (Karlsruhe Atmospheric Meso-scale Model), and a comparison between KAMM and WAsP (Wind Atlas Analysis and Application Program) analysis has also been done for some coastal locations. Predictions at 50m height show that the wind speed in the coastal areas may vary from 4m/s to 5.8 m/s. But as there is a strong seasonal and diurnal variation in Bangladesh so wind power density is quite higher than for locations having the same annual wind speed with a low speed variation. Some selected areas in Kutubdia, St. Martin’s, Sawndip, Hatya and Charfassion Islands and some of the coastal areas like Kuakata should have a fair potential as wind power density is above 200 w/m2.
Recent technology improvement also shows that manufacturer’s now developing low capacity wind turbines with a lower cut-off speed at around 2.5m/s. So it may be concluded that measured wind speed at hub height of 50m or above could give an accurate assessment of wind energy and its prospect of utilization in Bangladesh
Progressively detailed and updated information on energy from Coastal wind in Bangladesh will be provided in this site;

As an important Island in Bangladesh, Kutubdia has been chosen first. The Island is very much important for salt processing and fishing. More then 0.12 million people are living in this Island where around 3% of them are getting electricity. Wind energy assessment over the Island has been done in Renewable Energy Research Centre, University of Dhaka to find out the potential sites for wind generators. It is found that the Island is very much suitable for small wind electricity system.
